Just read it.

It's not even a page long, and it's basically "we're reporting that this was possible in a lab". No follow-up. Doesn't count! ;)

Well, I edited the post slightly-- there are more confirmed diodes/wavelengths ;)

1994? Green diodes were considered "impossible" in 1994 ;) They have greens on this page, bottom says copyright 2004-2012

1University of Illinois, Department of Electrical and Computer Engineering and Microelectronics Laboratory, Urbana, USA

2Hewlett-Packard, Optoelectronics Division, San Jose, USA

The first current injection lasing action in AlGaInP/Ga0.65In0.35P heterostructures grown on commercially available GaAs0.6P0.4 substrates is reported. At 77 K, laser diodes exhibited threshold current densities of 900 A/cm2 with yellow stimulated emission near 5735 Å. This is the shortest current injection lasing wavelength ever achieved in a III-V compound semiconductor.

History: Received 30 September 1994

OH on the first link. Hm, then that is a shocker.
Guess they're not commercial because theres no real application for the things yet.

If we search through scientific journals/articles, it would probably be the case that all sorts of wavelengths have been undertaken in a lab.

That's not the point of this thread. Critical here, is the fact that there must be some evidenced effort/intention/undertaking to actually create a diode. I won't say that there has to be a view to commercialization, because that's a touchy way to phrase it. But there has to be some evidence of a stated intention to actually release the diode as a tangible product.

Don't know if you are still working on this thread rhd but felt this is quite a practical piece of information if someone was to search for available diodes. Thorlabs has some 100mW 633nm diodes:

Good pricing on Avnet:

I wonder if DTR can get these for us giving the Ushio diodes he already stocks.
